Embodiment Construction
[0042] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0043] Such as Figure 1 to Figure 26As shown, the present invention is a centrifugal fan blade injection molding mold, which includes a moving module 2 and a static module 3, a sliding mold core 4 is arranged on the moving module 2, because the curved air duct 11 of the fan blade 1 The end face is a circular arc angle 12, and it is impossible to realize one-time demoulding during injection molding; in order to facilitate the one-time demoulding of fan blade 1 during injection molding, the moving module 2 is provided with a plurality of chutes in an annular array 21. The number of chute 21 is the same as the number of air passages 11 of fan blade 1. A sliding core 4 that can slide along the chute 21 is provided in each chute 21, and a sliding core 4 is provided on the chute 21 The block 5 of the sliding stroke and fixedly connected with the moving module 2 ...

The invention relates to a centrifugal fan blade injection moulding die, which mainly solves the technical problems that the conventional fan blade can not realize one-time die removal and the like. The centrifugal fan blade injection moulding die is characterized in that a sliding die core comprises an upper sliding block and a lower sliding block, wherein the front end of the lower sliding block is slant; the upper end surface of the upper sliding block is provided with a circular arc curved surface matched with a circular arc angle of the upper end surface of a fan blade air flute; the end part of the circular arc curved surface is provided with a positioning table; the upper sliding block and the lower sliding block are movably connected and can slide along an inclined surface of the front end of the lower sliding block; and the shapes of the front ends of the upper sliding block and the lower sliding block are matched with the fan blade air flute. The centrifugal fan blade injection moulding die has the beneficial effects that the sliding die core is set into a split structure to form the upper sliding block and the lower sliding block; the front end of the lower sliding block is provided with the inclined surface to movably connect the upper sliding block and the lower sliding block so as to enable the upper sliding block and the lower sliding block to form synchronous linkage; during die pulling, the upper sliding block horizontally slides along the inclined surface of the lower sliding block to be respectively pulled out from the fan blade air flute by in a layering way in sequence; and therefore, the technical problem that the conventional fan blade air flute can not realize one-time die removal because of the circular arc transition angle is solved.
Description
technical field [0001] The invention relates to an injection mold, more specifically to a centrifugal fan blade injection molding mold, which is mainly used in the mold industry. Background technique [0002] Fan blades are the core components of centrifugal fans, such as figure 1 , figure 2 As shown, since the existing fan blade 1 has an arc-shaped air duct 11, and the upper end surface of the air duct 11 is provided with a circular arc angle 12, the core pulling cannot be completed during injection molding, and the one-time use of the fan blade 1 cannot be realized. Injection molding. Therefore, for many years, most domestic enterprises have relied on importing wind blades 1 from Germany, Taiwan and other regions. However, due to the long-term technical blockade of Western countries against China, the one-time demoulding technology of domestic wind blades 1 has not been solved. A buyer's market for wind blades 1 has formed in China, and they do not have the bargaining ...
